Tooll whom it may concern:

Be it known that 1, ROBERT .loLIUs MAn'riN, a subjeet of the King of Saxony, and a resident of Antonsthal, near Schwarzenberg, in the Kingdom of Saxony and Empire of fiermany, have invented new and useful Improvements in Paper-lviaking Machines, of which the followlqoz' is a specification.

My invention relates to paper-making machines.

The machine constructed according to my said invention has an endless sieve with an adjustable sieve and the suction part being adapted to'be adjusted independently of each other in such a manner that either part may be given any'desircd drop or fall, the shaking -nioveiiient not beinq transmitted to the suction part.

Owing to the independent adjustability of the sieve table and the suction part the sieve may be placed at any desired inclination, so that the paper pulp which,.

by the pressure due to the stemming in. front of the straight-edges, passes precipitately upon the sieve and spreads thereon, will Without flowing bach gradually obtain. the same velocity as the sieve andthus insure the un l'ormation of the paper. I

it n en found by experience that the trouble caused by the undulating bac'lrtlow of the paper pulp increases with the velocity of the machine. In this way the thickness of the web of paper bccomcs'irrcgular, thus giving the paper a bad appearance. Accordingly a thin paper will, when the sieve moves at a great velocity, require a greater drop or fall of the sieve than a thicker paper with a' sieve moving at a small velocity.

. As with the improved arrangement the paper pulp can be caused in a simple, manner togspreadrapidly, the working may take-placcwith less diluting substances, so that the paper pulp will already contain less water as it llows upon the sieve, and will reach the suction apparatus in a drier and more coherent condition. Thus I prevent the filling or loading substances and the like being washed and drawn in an excessive manner by the great quantity of waterand by the intensely operating suction apparatus from the on der side of the web-oi paper so as to occasion differences in the paper on its two sides,-whicl1 is particularly troublesome in the case of papers, such as illustration and colored papers, which contain much filling orloading substance. The marking of the sieve is also les noticeable. Furthermore, the improved arrangeinent enables either the suction part or the sieve table to be given any desired fall or drop by itself, and to be so adjusted that the sieve will always lie upon the suction apparatus and that the proper operation of the same will be insured. Lt the same time itzis'possible with the improved arrangement 'tii start the shaking movement for the sieve table alone, while in the case i of the well-knownariahgement, where the sieve table and suction part are adjusted together such movement must also be transmitted to the suction part and requires a great expenditure of power.

By arranging the pivots of the sieve table in proximity to the middle of the sieve table's. small movement of the support will cause the inclination to be greatly changed and theweights to be balanced.

Several constructional forms of the machine are represented by way of example in the accompanying drawings.

Figure 1 is an elevation showing an adjustable sieve in the inclined position. Fig. 2 is a similar elevation representing the same in the horizontal position. Fig. 3 is'a plan showing the arrangement of the sieve. Figs. 4 and '5 are diagrams illustrating two constructional forms The sieve table a and the suction part b of the sieve c are each pivoted at such a point that the two parts, while a good passage from one to the other is retained, can be adjusted to different inclinations. The pivot of the suction part is situated at the end of the same at (1; while the pivot oi the sieve 'table is arranged at a between the ends of the same.

The-adjustment is effected after loosening the guide bolts h adapted to be displaced in the slits f of the frame {7 and provided at the adjoining ends of the sieve tableand suction part by turning a crank t which through the. intervention of chain gear k m sets the shaft n and worms 0 in motion and, by means of worm wheels forming nuts and engaging the said worms, effect the axial displacement of the supports 7), these supports being provided with screw threads and prevented from turning. The supports 10 are furnished with ball joints in the Well-known manner.

Two different positions are'shown in Figs. 1 and 2.

The simultaneous adjust-ability. of'the sieve table and the suction part may also be achieved in various other ways. Thus for instance Figs. 4 and 5 show two constructional forms, in which the sieve table a is suspended so as to enable the same to make a rocking movement, the adjustment of the two parts a and b the alil of a screw-threaded spindle q.

In constructional form representedin Fig. ithe pivot hi the sieve table is below and the sieve is at the top, while in the constructional form shown in Fig. 5 the pivottis above, and the sieve is below.

Wh t l claim as my invention, and desire to secure by Letters .Patent, is v 1. In a inuclliue of the class described, the combination of on adj ustable oscillatory sieve table, an adjustable oscillatol-ysuction part, the said stove tableand suction part being loosely connected, and means for slmultancously rnlsing'and lowering the said sieve table and suctlon part, substantially as herein set forth; p

2. In a machine of the class described, the combination or an adjustable oscillatory sieve table having its pivot at :,point between the two ends of the same, an djustable being effected from. the point where they adjoin with oscillatory suction part, and means for siuiuitaneously' raising and lowering the said sieve table and suction part, substantially as herein set forth.

3. In a machine of the class described, the combination of an adjustable oscillatory'sieve table having its pivot at. a point between"tlredgwo ends oi 'the same, an adjustable oscillatory suction part. and means for adjusting the said table and suction part-lt'roln a single point, substantially as herein set forth. Y 7

4. In a machine of thee-lass described, the combination of an adjustable oscillatory sieve table, an :uljusi'able 0scillatory suction part, adjustable supports for the said slevie table and suction part, and means for adjusting these supports from a single point, substantially as herein set forth.

In-n machine of the class described, the couibination of an adjustable oscillatory sleve table, an adjustable 0scillatory suction part, adjustable supports for the said sieve table and suction part, said supports being provided with a screw threaded portion. a shaft for turning the supports from a single point, worms secured to the said shaft, worm wheels gearing with these worms and engafzing the screw threaded portions of the aforesaid supports, substantially as herein set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing: witnesses.
